Delta airfare deals from LaGuardia; purchase by 8/7 for fall travel

Delta is dealing discounts from LaGuardia to many USA destinations.  I just snagged a $237 round-trip fare to Indianapolis next month, to attend the Society of American Travel Writers (SATW) annual conference.  Here’s what else is on sale from Delta, for purchase by tomorrow, for travel later this summer and fall — one-way fares to Detroit $100, $120 to Minneapolis/St. Paul, Nashville and New Orleans.  There also are sale prices on round-trip fares from JFK and Newark airports
